Description
Technical field
The present invention relates to wind fan, particularly to a kind of Efficient jet flow fan.
Background technology
Bladeless fan, is also called " wear gloomy air supercharge ", induced draft can be produced, due to there is no blade, therefore relatively
Tradition will not cover dust for having blade fan, and uses more convenient, safety.Existing bladeless fan includes in structure
Jet ring, the impeller being driven by motor, and connect the gas channel of jet ring inner chamber and impeller superjacent air space, in narrow annulus
The air outlet of shape is arranged on jet annulate shaft to side.Its operation principle is that the impeller of rotation produces air-flow upwards, and air is inhaled
Enter fan base interior, air-flow enters in incident flow ring inner chamber through gas channel, forwards spray through narrow circular air outlet and
Go out and form jet, effluxvelocity can increase 15 times about compared with the air velocity in gas channel, periphery and jet are driven by jet
Air on rear side of ring together forms the air-flow of flow forward.According to jet current principle, in certain point, jet-stream wind will form one
Jet is bored, and the jet theory that narrow circular air outlet produces will form the jet cone of ring-type, but be subject to sparge ring and air-out
The impact of mouth structure, close to half range jet cone can by air outlet outside sparge ring outer wall block so as to the sky of institute's winding
Tolerance is greatly reduced, and jet effect is greatly affected, and does not give full play to the jet of efficiency simultaneously and jet ring outside wall surface is rubbed
Wipe and produce noise, the efficiency of therefore existing bladeless fan and quality still have much room for improvement.
Content of the invention
The technical problem to be solved is to provide a kind of Efficient jet flow fan, to give full play to jet effect, carries
The wind-producing efficiency of high bladeless fan, or reduce power consumption in the case of producing identical use air quantity.
The technical solution adopted for the present invention to solve the technical problems is as follows:
The Efficient jet flow fan of the present invention, including the impeller being driven by motor, and is located at the gas channel above impeller,
It is characterized in that: further comprising a cyclone ring with annular vortex chamber, annular vortex chamber is intersected with gas channel upper end, in eddy flow
Circumferentially spaced on the internal ring of ring it is provided with shunting limb；The outer end of shunting air flue in each shunting limb and the annular eddy flow of cyclone ring
Chamber is tangentially intersected, inner then communicate with the spray chamber positioned at cyclone ring axial centre position, is provided with axial injection outside spray chamber
Nozzle.
The invention has the beneficial effects as follows, jet effect can be given full play to, the wind-producing efficiency of bladeless fan can be significantly increased
And quality；On the premise of being likewise supplied with high safety in utilization, wind-producing amount is big, and wind speed is more uniformly distributed, and noise is lower, except can be used for
Outside life office occasion, it may also be used for commercial production；Power consumption can be greatly reduced in the case that generation is identical with air quantity, pass through
Configure production cost and the use cost that lower-powered motor can reduce bladeless fan.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
With reference to Fig. 1, Fig. 2 and Fig. 3, the Efficient jet flow fan of the present invention, including the impeller 12, Yi Jiwei being driven by motor 13
In the gas channel 21 of impeller 12 top, it also includes a cyclone ring 30 with annular vortex chamber 30a, annular vortex chamber 30a
Intersect with gas channel 21 upper end, on the internal ring of cyclone ring 30, circumferentially spaced being provided with shunts limb 31.In each shunting limb 31
The outer end of shunting air flue 31a tangentially intersect with the annular vortex chamber 30a of cyclone ring 30, the inner then with positioned at cyclone ring 30 axially
The spray chamber 40 of center communicates, and is provided with axial injection nozzle 41 outside spray chamber 40.During bladeless fan work, air-flow is through air-flow
Passage 21 enters and forms swirling eddy acceleration, supercharging in annular vortex chamber 30a, and enters spray chamber 40 through shunting limb 31, then warp
Axial injection nozzle 41 is penetrated forward, stops because injection nozzle 41 periphery has no other tectosomes, therefore can form complete penetrating
Flow cone, jet effect is given full play to, and this no query can be significantly increased the wind-producing efficiency of bladeless fan, or is producing phase
Power consumption is greatly reduced with the case of air quantity, by configure lower-powered motor reduce bladeless fan production cost and
Use cost.
